Rocker Billy Corgan has sold one of his two Chicago-area properties, a vintage, 3,700-square-foot condominium unit on the Gold Coast for $2.5 million, records show.

The Smashing Pumpkins lead singer and chief songwriter had spent more than four years trying to sell his in-town condo, which he bought in 2002 for $2.95 million. His main residence is a mansion on Lake Michigan in Highland Park that he bought in 2003 for $6.8 million.

The renovated, full-floor Gold Coast condo unit most recently had been listed for $2.85 million. He first listed it for $5.5 million in September 2008. He subsequently reduced his asking price to $4.35 million, $3.875 million and $3.55 million before dropping it to $2.85 million in June 2011.

In a converted mansion that has elements designed by noted architect David Adler, the six-room unit has two large bedrooms, 2-1/2 baths, four wood-burning fireplaces, walnut parquet floors, a reception room, 10-foot-plus ceilings, a library, an oak-paneled living room, a balcony, a large terrace and a deeded parking space.

Corgan's listing agent, Marla Nyberg of Koenig & Strey, could not be immediately reached for comment late Friday. The identity of the buyer is not yet shown in public records.

Corgan also owns a 3,267-square-foot house in Beverly Hills, Calif., that he bought in mid-2009 for $3.85 million.
